can't run a project using the UART

Hi all--

I built a default "hello_world" project which references the "standard" example .ptf. I also chose the default setting to have a system library autogenerated.

I then went into the system library's Properties settings and changed the stdin, stdout, and stderr dropdown-box settings to "uart1," (not the jtag_uart, but uart1) and did "Build Project," which successfully built the application and syslib projects.

I uploaded the "standard" .sof file to the board, then went back to the IDE and chose "Run As..." > "Nios Hardware" on my hello_world project.

The console window response I get is:

---

nios2-terminal: can't open uart: No such file or directory

---

Anyone have an idea why? I don't believe the "standard" project even HAS something called "uart." It has a "uart1," and a "jtag_uart."

There must be something basic I'm not doing, but I have no idea what. Any comments would be appreciated.

Brian

    For anyone who cares, this problem seems to have been just caused by a misconfiguration of the terminal software I was using. Apparently the nios2-terminal software gets told to use whatever port is chosen for "stdout." My terminal software was misconfigured, so apparently when nios2-terminal tried to output:

    nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

    ...it didn't succeed, and responded with the "can't open uart" message.

    I love being new. Not. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif
